Might want to start taking a look at your intake, intake tubing, MAF sensor, etc... I had a "Service Engine Soon" light...ended up costing nearly $1700 to repair the beast, but it runs like a champ. Should've seen some of the tubes I needed to replace!

why don't you check the o2 sensor, that was happened to me.and also chech the MAF sensor,intake tubing.good luck.

thanks guys for reply,,,
i know that the o2 sensor is on the exust pipe !,,but how do i check them? and where exactly is the maf sensor? is there a way to chack them my self? thanks

You need to get the code first before do anything.

If you don't have a reader, go to Auto Zone. They will read the computer codes and tell you what is going on. They will not reset your light though. After needing to do the same for my wifes VW three years ago I just bought a reader. They come in many flavors.

You can't just change your points and condensor any more. For ALMOST any problem you will have the reader is just the place to start.
